Lennox G43UF-36C-090H Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence which may be needed in order to defrost your outdoor unit. It is relayed information from a temperature sensor which is near the condenser somewhere, in order to ascertain when to begin.
What red flags are there that my AC defrost sensor board is crapping out?
- The defrost feature never runs even though there is a lot of frost on the external unit
- The main board may show an error of some type when the defrost control board refuses to initialize properly
- The AC may end up not running due in part to way too much frost build-up
